Function f is an exponential function
By what factor does the output value increase as each input value increases by 1?
Answer:
4
Step-by-step explanation:
You are given a table of function values in which x increases by 2, and you want to know the factor by which f(x) increases when x increases by 1.
FactorLet k represent the factor by which f(x) increases when x increases by 1. This means ...
f(2) = k·f(1)
f(3) = k·f(2) = k·(k·f(1)) = k²·f(1)
64 = k²·4
k² = 64/4 = 16
k = √16 = 4
The output value increases by a factor of 4 as the input value increases by 1.
__
Additional comment
The table values would also be obtained if the factor of increase were -4. That is, f(x) = -(-4)^x would give the same table. In that case, f(x) would not be a continuous function.

Ajit has five coins that make up $.51 what coins does Ajit has
Answer:
Step-by-step explanation:
Ajit has 5 coins in total
1 quarter = 25 cents
1 nickel = 5 cents
2 dimes = 20 cents
1 penny = 1 cent
The required coins that Ajit has are 1 quarter, 1 nickel, 2 dimes, and 1 penny.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Let,
Quarter = x
Nickle = y
Dimes = z
penny = a
So, accoding to the quesiton
0.25x + 0.5y + 0.10z + 0.01a = $0.51
Ajit has 5 coins in total
So that the sum of x + y + z + a = 5
Apply hit and trial,
1 quarter = 25 cents
1 nickel = 5 cents
2 dimes = 20 cents
1 penny = 1 cent
Total coins value = $0.51
Similarly, various cases can be determined.
Thus, the required coin that Ajit has is 1 quarter, 1 nickel, 2 dimes, and 1 penny.

Is the system of equations consistent and independent, consistent and dependent, or inconsistent?
y=−3x+12y=−6x+2
Select the correct answer from the drop-down menu.
consistent and independent
The system of equation is consistent and independent because it has one unique solution.
How to solve system of equation?If a system has at least one solution, it is said to be consistent . If a consistent system has exactly one solution, it is independent.
Therefore, let's solve the equation,
y = -3x + 12
y = -6x + 2
Using substitution,
-6x + 2 = -3x + 12
-6x + 3x = 12 - 2
-3x = 10
x = - 10 / 3
y = -6(-10 / 3) + 2
y = 60 / 3 + 2
y = 20 + 2
y = 2
Therefore, the system of equation is consistent and independent.

Perimeter equals ______________ meters
Answer: 50
Step-by-step explanation:
10+15+6+4+6+11= 50
Edit=
We can see that the length of one side is 10, and the width of one is 15. For the other side of the width, we can subtract 4 from 15 to get 11. For the other length, we can subtract 6 from 10 to get four. We also have to add in the 6 and 4 because they are parts of the border. (10+15+11+4+6+4)

What is parallel lines?
Parallel lines are coplanar, straight lines in geometry that don't cross at any point. When two planes in the same three-dimensional space are parallel, they never cross. Curves that maintain a set minimum distance from one another and do not touch or intersect are said to be parallel curves.
(8) Given: m || n
We have to find the value of x that makes m || n.
The lines m and n are divides by the line l of angle 90 degree.
⇒ 16x - 6 = 90
Add 6 on both sides,
16x - 6 = 90 + 6
16x = 96
Divide both sides by 16
16x/16 = 96/16
x = 6
Hence, the value of x is 6 degree that makes m || n.

Jack bought a tree to plant in his front yard. The tree grows at an approximate rate of 9 inches per year. After 4 years, the tree is 5 feet tall. Write an equation in slope-intercept form to find the height (in feet) of the tree, y, after x years. Then, find the number of years it will take the tree to reach 20 feet
The equation in slope-intercept form to find the height is y = 0.75x + 5 and the number of years it will take the tree to reach 20 feet is 24
The linear equation to find the height (in feet) of the treeThe given parameters in the question are
Growth = 9 inches per year
Length of the tree after 4 years = 5 feet
Convert inches to feet
So, we have
Growth = 0.75 feet per year
A linear equation of this scenario is represented as
Length = Growth * Number of years + Initial length
So, we have
y = Growth * x + Initial length
This gives
5 = 0.75 * 4 + Initial length
Evaluate
Initial length = 2
So, the equation is
y = 0.75x + 2
The number of years it will take the tree to reach 20 feetThis means that
y = 20
Recall that
y = 0.75x + 2
So, we have
0.75x + 2 = 20
Evaluate
0.75x = 18
Divide by 0.75
x = 24
Hence, the number of years is 24

{P1, P3, P4} (weight: 31) {P1, P3} (weight: 30)
What is the distribution?
The mathematical expression known as a distribution function expresses the likelihood that a system would adopt a certain value or range of values. The traditional examples include games of chance.
The voting system tells us that the quota is 30, that Player 1 has 17 votes (or equivalently, has a weight of 17), Player 2 has 15 votes, Player 3 has 13 votes, and Player 4 has 1 votes.
A coalition is any group of one or more players. What we're looking for is winning coalitions - coalitions whose combined votes (weights) add to up to the quota or more. So the coalition {P3, P4} is not a winning coalition because the combined weight is 13 + 1 = 14, which is below the quota.
So we look at each possible combination of players and identify the winning ones:
{P1, P2}( weight :32) {P1, P2, P4} (weight: 31)
{P1, P2, P3} (weight: 45) {P1, P2, P3, P4} (weight: 46)
{P1, P3, P4} (weight: 31) {P1, P3} (weight: 30)
Hence, these are the possible combination of winning players.

1,108 units. If x represents the number of production hours, which of the following inequalities symbolizes this situation?
The inequlity according to the given statement will be equal to 280 + 92(x) ≥ 1,108.
What is inequality?Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values. Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.

Rania redesigned the bottom of one of the Landing pools. the equation that describes the bottom of the redesigned pool is y = 2/5x -60 in this equation y represents the depth of the water and x is the distance a guest lands away from the far wall all measurements are in inches. How deep is the water in the pool where a guest lands in the water 36 inches from the wall?
A. Y=74.4 in
B. Y=38.4 in
C. Y=45.6 in
D. Y=60 in
Answer:
C. y = 45.6 in
Step-by-step explanation:
Given equation:
[tex]y=\dfrac{2}{5}x-60[/tex]
where:
y is the depth of the water (in inches).x is the distance a guest lands away from the far wall (in inches).If a guest lands 36 inches from the wall, then x = 36.
Substitute x = 36 into the equation:
[tex]\implies y=\dfrac{2}{5}(36)-60[/tex]
[tex]\implies y=\dfrac{2 \cdot 36}{5}-60[/tex]
[tex]\implies y=\dfrac{72}{5}-60[/tex]
[tex]\implies y=14.4-60[/tex]
[tex]\implies y=-45.6[/tex]
Therefore, the depth of the water is 45.6 inches (since -45.6 inches means it is that distance below the surface).

Stanley runs, swims, and bikes every day. During these workouts, he runs at 9 mph, bikes at 16 mph, and swims at 2.5 mph. Yesterday, he ran for half an hour longer than he swam, and his biking time was twice his running time. How long did Stanley run, swim, and bike yesterday if the total distance he covered was 64 miles?
what distance did stanley swim run and bike
PLEASE HELP
The time did Stanley run, swim, and bike yesterday if the total distance he covered was 64 miles is 1.5 hrs, 1 hrs, 3 hrs. The distance is 13.5 miles, 2.5 miles , 48 miles.
How to find the distance and time?Let t represent the time he ran
Let t -.5 represent time he swam
Let 2t represent the biking time
Hence,
9t + 2.5(t-.5) + 16(2t) = 64
9t + 2.5t - 1.25 + 32t = 64
Collect like terms
43.5t = 64 + 1.25
Divide both side by 43.5t
t = 65.25/43.5
t = 1.5 hrs (Time he ran)
So,
Time he swam
t -.5 where t is 1.5 hrs
1.5-.5 = 1 hr (Time he swam)
Biking time
2t where t is 1.5 hrs
2(1.5) = 3 hrs (biking time)
Distance of each
1.5(9) = 13.5 miles (running)
1(2.5) = 2.5 miles (swimming)
3(16) = 48 miles (biking)
Total distance = 13.5 miles + 2.5 miles + 48 miles
Total distance = 64 miles
Therefore the time is 1.5 hrs, 1 hrs, 3 hrs and the distance is 13.5 miles, 2.5 miles , 48 miles.
